Optimization of Design Parameters of Dielectric Resonator Antenna (DRA)

Dielectric Resonator Antenna (DRA) is one of the most imperative antennas used extensively in wireless communication. The spherical Dielectric Resonator Antenna (DRA) is investigated first time. With an optimum combination of radius and permittivity, a maximum bandwidth is attained. The proposed spherical DRA is resonated at frequency of 3.75 GHz. In this paper, proposed spherical DRA with annular feed ring loading resonates at multiple frequencies with gain and bandwidth enhancement. The Dielectric Resonator Antenna (DRA) is shape independent.
